Title: Improvements in or relating to the manufacture of float glass
IPC: C03B18/16
Filed: 1968-08-12
Abstract: 1,270,934. Flat glass manufacture. PILKINGTONBROS.Ltd., and G.A. DICKINSON. 24 July, 1969 [12 Aug., 1968], No. 38561/68 Heading C1M. In the " float " glass process of manufacturing " thick " glass by physically halting the lateral flow of glass using fenders 14, 15 when the glass is at the required thickness, temperature equalization of the bath is obtained by causing the molten metal underlying the glass between the fender sections 18 to flow towards the side of the bath where the flow diverted downstream and confined to the sides of the bath and finally allowed to disperse downstream of the fenders. The flow may be obtained using linear induction motors 42, 43 and diverted by two pairs of baffles 46, 47 and 49, 50. The fenders 14, 15 each comprise three graphite trough-shaped sections 18, 19, 20 having flat faces engaging the molten glass layer and a pipe carrying cooling fluid disposed within the trough. The first sections 18 are supported on spacer legs (32) while the other sections 19, 20 include plates (35) which extend to the tank bottom and thus confine the metal flow to the sides of the bath.

Title: Gating circuit and magnetic storage device incorporating such a circuit
Inventor: OWEN CHARLES EDWARD
IPC: H03K5/00
Filed: 1967-08-26
Abstract: 1,126,160. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 26 Aug., 1967, No. 39369/67. Heading G4C. [Also in Division H3] A circuit for selecting regularly recurring pulses e.g. from a magnetic disc store comprises a gate and a ramp generator, the pulses providing one input to the gate and the other input being provided by the ramp when it exceeds a controlled value, the flyback of the ramp having a constant amplitude irrespective of ramp length and being initiated by the output of the gate. As applied to a magnetic disc store, binary data D (Fig. 2a) is represented by the presence and absence of a pulse between succesive clock pulses C. The data pulses cause the recorded clock pulses to be pushed apart, as shown dotted, but as the flyback is of constant amplitude the point at which the ramp (Fig. 2b) crosses the threshold T of the gating circuit is not affected. The input pulse train 2(a) alternatively may be derived (Figs. 3a-3g, not shown) from a signal (Fig. 3a) in which a change of binary data between its two values is represented by a change of phase of the signal. The signal is differentiated (3c) squared (3d) and produces pulses at the resulting leading and trailing edges (3c and f). These are combined to form the derived train (3g). Circuit details (Fig. 1).-The input pulses (2a) are applied at 13 to gate 14. The output pulses of the gate discharge capacitor 18 through diode 19 and the trailing edge transfers the charge to a Miller capacitor 21 to produce a determined magnitude of flyback. Capacitor 21 then discharges linearly to produce a ramp voltage (2b) at the input of transistor 32. The input of this transistor comprises a circuit which biases it to allow a predetermined portion of the end of the ramp to pass through transistors 32 and 37 to produce pulses 2(c) which are applied to the other input of gate 14 and thus to allow the next clock pulse to pass. The output from 32 is also applied to a gate 15 to block the clock pulses and allow the data to pass. An averaging circuit 26<SP>1</SP>, 27 controls the rate of discharging of the Miller capacitor 21 so as to stabilize the amplitude of the sawtooth wave.

Abstract: 336,506. Electrolux, Ltd., (Assignees of Lenning, A., and Taylor, R. S.). Jan. 4, 1929, [Convention date]. Thermally - actuated valves. - In refrigerating. apparatus heated by a gas burner, two valves 10, 20, Fig. 1, are arranged in series in the gas supply conduit, one valve 10 being closed to cut off the gas supply when the temperature of the flame falls, and the other being closed when the temperature of a heat delivering part, such as the absorber 31 or the condenser 19, rises unduly. A fuel regulating valve 30 controlled by a thermal element. 61 near the evaporator 22 may also be employed. The refrigerating apparatus shown is of the continuous-cycle inert gas type, including a generator 11, rectifier 18, and gas heat exchanger 28 of the known kind. The valve 10 mav consist of a lift valve 46, Fig. 2, connected to a snapaction diaphragm 48 in a casing having a member 50 extending over the burner 5. When the flame goes out the diaphragm 48 snaps to close the valve and may be reset by applying the heat of a match to the casing. The valve 20 may be similar and the casing of the diaphragm may be united as by welding to the absorber &c. It opens of itself when the overheated part cools to normal temperatures. The valve 30 may be of the bellows type with a bye-pass 62 around it. The valves 20. 30 may be combined in one casing, as shown in Fig. 4. The snap-action diaphragm 56 is arranged in a chamber 73 communicating by a tube 74 with a thermal capsule 73 subject to the influence of the heat delivering part, and the diaphragm carries a valve member 54 adapted to close a passage 66 leading from the chamber 67 of the regulating valve to the gas conduit 64.

Title: Closure valve assembly for the outlet port of a pressure vessel

Abstract: 907,229. Hydraulic accumulators. MERCIER, J. Dee. 10, 1958, No. 39871/58. Class 69 (2). An hydraulic accumulator comprises a deformable partition 14, Fig. 1, in a rigid container 11 and an outlet port closable by a closure member 36 controlled by movement of the partition against the action of resilient means 42 of the type which, over a predetermined range of deformation exerts a force arranged to progressively decrease with increasing deformation of the resilient means and oppose the force exerted by the expanding partition as it moves to stop flow through the port. The closure member consists of a valve 37 which is supported in a disc 31 mounted in a tubular outlet 16 and is urged to the open position by spring steel strips 42, spring washers or coil springs 111, Fig. 6. All the resilient members have the characteristic that, under pressure applied by the partition, as they are initially deformed over a predetermined range measured along the abcissa 181 of the graph, Fig. 13, to the point A, the force exerted by the members to restrain closing of the valve progressively increases and, past this point, progressively decreases. The members may be initially deformed to the point B so as to make available a considerable force to retain the valve in open position. In another embodiment, the tubular member 71, Fig. 4, has passages 73 which may be progressively closed by the expanding partition deforming a spring- steel disc 76. In a further embodiment, the closure member consists of a cup-shaped portion 144, Fig. 8, which has holes 147 for the passage of the fluid and is riveted to a spidershaped spring 155 and a head 151 of sheet steel, plastic, hard rubber or the like arranged to abut the tubular member or the container when the partition 134 moves the assembly downwardly against the spring 155.

The tool body has wedge-shaped projections 73 which engage a complementary groove 83 in the disc 81 to prevent relative rotation between the tool body and disc. The collet 18 has slots 23 the terminal portions of which are filled with elastomeric material 27. In a modification (Figs. 3, 4, 5, not shown) the collet is received in a bushing member (15) inserted in the boring bar and the tool body (93) is itself formed at its end as a collet having a cap nut (97) adapted to cause the tool body to grip a replaceable tool bit (90). The tool bit which is keyed to the tool body may be adjusted in position in the tool body by a screw (92) which projects adjustably from its inner end and rests on the base of the recess in the tool body.
